2 Claims. (01. 156-16) The present invention refers to slidable shutters to be used in combination doors and Windows, and its principal object isto provide a new type of slidable, flexible shutters, adapted to be incorporated in door and window structures and to be readily lifted and lowered by means of a corresponding shutter operating mechanism.

The slidable shutter constructed according to our invention is composed of a plurality of small horizontal rods conveniently connected and articulated to each other so as to make the same flexible. The articulation of one rod to the next following one is secured by a longitudinal projection of one rod engaging a corresponding longitudinal groove in the next one, and the connection of the rods to each other is obtained by a flexible band. fixed to the end rods and passing through suitable perforations provided in each of the intermediate rods of the shutter. In order to allow free passage of air through the shutter, longitudinal oblique mortices may be provided in said rods.

Another object is to provide means for fixing an operating band to the upper shutter rod, said band serving to lift and lower the shutter by means of a corresponding lifting mechanism of the type adapted to cooperate with a flexible band or belt.

With these objects in view, and others which will appear as the specification proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended thereto.

In the accompanying drawing which illustrates the invention and wherein like numerals of reference indicate corresponding parts in the different views:

Figure 1 is a perspective view of the shutter constructed in accordance with our invention;

Figure 2 is a detail view of one rod of the shutter;

Figure 3 is a cross section taken along the line 33 of Figure 2;

Figure 4 is a front view of two adjacent rods of the shutter;

Figure 5 is a cross section taken along the line 55 of Figure 4.

With reference to the accompanying drawing the shutter constructed in accordance with our invention, is composed of a plurality of small horizontal rods 1 with conveniently curved outer surfaces as shown in Figure 3. In order to make the shutter flexible. the rods are articulated to each other by a longitudinal projection 2 of one rod engaging a corresponding longitudinal groove 3 provided in the next following one, said groove being wide enough to permit free articulation of the engaging projection of the adjacent rod. For the purpose of connecting the rods to each other in order toform the desired shutter, a fiexible band 4 is passed through corresponding perforations 5 provided in all of the rods 1 and is fixed to the upper rod 6 and lower rod 7 by means of screws or rivets 8.

The flexible band 4, according to Figure 1, extends beyond the lower rod 7 for the purpose of its being passed through a shutter lifting mechanism of the type comprising friction rolls for imparting motion to the shutter by means of said v band 4. It will be understood that in the case of using such lifting mechanism and of extending said band 4 beyond the lower rod 7, this nevertheless is fixed to said rod within the perforation produced therein.

For the event that the shutter is to be operated by means of a shutter lifting mechanism which employs special belts, constituting the mechanical connection with the shutter, these conveniently are fixed to both ends of the upper rod 6, and for this purpose we provide a special element 9 as shown in Figure 1. This element consists of a conveniently bent metal bar fixed at one end to said upper shutter rod 6 and at the other end to the endless belt 10 by means of rivets 11 or like fastening means, and its application to said belt preferably is made at the point where both ends thereof are connected to each other, so that this device at the same time serves to reinforce the joint of said endless belt; in said figure only a portion of the latter has been shown.

It will be understood that the slidable, flexible shutter constructed in accordance with our invention, is particularly advantageous, in View of its flexibility, which may be increased as desired by diminishing the cross section area of the different shutter rods. Thus this shutter is specially adapted to be used in connection with combination doors and windows having a slid- 1w able, flexible shutter incorporated therein, in which the same is desired to follow loop forming guide grooves, and in such cases it may be convenient to have the different shutter rods constructed so as to present curved inner surfaces .195

which will facilitate their moving along said loop forming grooves.

It has to be understood that the present invention is by no means limited to the form of the shutter and of the different rods as illusmy trated, but that the same may be as well of any other desired form. Further, in Figure 1 we have shown the shutter comprising but one flexible band 4 for connecting the rods to each other, whereas if desired, supplementary bands may be used in order to increase the stability of the shutter. Other similar modifications may be introduc'ed in the device without departing from the scope of the invention as set forth in the following claims.

Having now particularly described and ascertained the nature of oursaid invention and in what manner the same is to be performed, we declare that what we claim is:

1. A slidable, flexible shutter for combination doors and windows, comprising a plurality of interconnected and articulated horizontal rods each having a longitudinal projection and a corresponding groove, a longitudinal projection of one rod engaging a corresponding longitudinal groove provided in the next following one, one or more flexible bands connecting said rods to each other, said rods having perforations, said bands being fixed to the upper rods and passing through said perforations in all of the intermediate rods,

and means for connecting the shutter with a corresponding shutter operating mechanism.

2. A slidable, flexible shutter for combination doors and windows, comprising a plurality of interconnected and articulated horizontal rods each having a longitudinal projection and a'corresponding groove, a longitudinal projection of one rod engaging a corresponding groove provided in the next following one, said groove being wide enough to permit free articulation between adjacent rods, one or more flexible bands connecting said rods to each other, said rods having perforations therein for passing therethrough said flexible bands, means provided at each end of the upper shutter rod for fixing thereto a belt for connecting the slidable shutter with a corresponding shutter operating mechanism adapted to lift and lower said shutter by means of said belt, said means consisting of a metal bar conveniently bent and fixed at one end to said upper shutter rod and at the other end to said belt by means of rivets or the like.
